"Turns out, the behavior is a critical part of incubation, and each species may have its own egg-turning recipe to hatch a healthy chick, a new study shows.
Scientists believe that most birds rotate their eggs to ensure that the embryo gets enough albumen—the mixture of water and protein that makes up the "egg white" part of an embryo and provides nutrients to the developing chick."
